Hello,
According to ?as.logical:
"as.logical attempts to coerce its argument to be of logical type. For
factors, this uses the levels (labels)."
However,
> as.logical(factor(c("FALSE", "TRUE")))
[1] TRUE TRUE
Shouldn't it be the same as:
> as.logical(levels(factor(c("FALSE", "TRUE"))))
[1] FALSE TRUE
according to the documentation? Did I miss something here?
